Welding inspection ensures that welded joints are safe, strong, and meet required quality standards. Even a small weld defect can cause leakage, structural failure, or shutdown — therefore inspection is essential.
Types of Welding Inspection
1. Pre-Welding
- Material & grade verification
- WPS approval
- Welder qualification
- Joint fit-up check
2. During Welding
- Welding parameters monitoring
- Root pass & inter-pass temperature
- Visual monitoring
3. Post-Welding
- Visual Inspection (VT)
- NDT: PT, MT, UT, RT
Common Standards
- ASME Sec V & IX
- AWS D1.1
- API 1104
- ISO 5817
- IS 817 / IS 9595
